The question of how long it takes to die after a brain hemorrhage cannot be generalized, but depends on the size of the hemorrhage and the severity of the patient’s condition. If the brain hemorrhage is relatively large, the patient directly enters a comatose state, brain herniation, such as severe coma, dilated pupils, incontinence, etc., is in a state of near death, and if the family gives up treatment, the patient may die within a few hours or even 1-2 days of severe respiratory and circulatory failure. If treatment is aggressive, emergency craniotomy is required for hematoma removal, plus decompression therapy with debridement, the patient may be better, barely alive, in a long-term vegetative state or with severe disability. In severe cases, severe cerebral edema occurs in about 1 week, and if the patient does not survive the cerebral edema period, the patient may slowly develop organ failure and slowly die. If the amount of bleeding is small, the patient’s recovery is generally good after conservative treatment or surgical treatment. Therefore, how long it takes to die after a brain hemorrhage depends on the severity of the condition.
